How does it work and where does big money come from? Everybody knows that currency exchange rates change all the time. When a currency becomes more expensive in comparison with another, people holding their money in the first currency may be winning while those who are holding their savings in the other currency may be losing because their currency has become cheaper in relation to the first one. Such changes occur every second, so if you buy a currency which is about to rise in price and sell it after the rise, you get the difference between the buy and sell prices as your profit. That is what is called currency trading or Forex trading.
